HPLC with ELSD Analysis of Oligomers in Extracts
High-Performance Liquid Chromatography (HPLC) coupled with Evaporative Light Scattering Detection (ELSD) is a powerful analytical technique widely used for the separation and quantification of oligomers, particularly in complex matrices such as pharmaceutical extracts. This service focuses on characterizing low molecular weight compounds that are often difficult to detect using traditional UV-Vis or other chromatographic methods.
The process begins with careful sample preparation, where the extract is prepared according to strict protocols defined by international standards (ISO 10350, ASTM D6872). The oligomers present in the extracted matrix are then separated through a reversed-phase HPLC column. Following separation, the eluted components pass into the ELSD unit which detects them based on their mass rather than their absorbance. This allows for accurate quantification even when dealing with compounds that do not have chromophores or UV-active groups.
The method is particularly advantageous in the medical device sector due to its precision and sensitivity, enabling detection of potential contaminants at extremely low levels. Compliance officers will appreciate how this service helps meet stringent regulatory requirements set forth by the FDA, EU MDR, and other global standards regarding extractable and leachable materials. For R&D engineers, it provides critical insights into material interactions during development stages.
The use of HPLC-ELSD ensures reliable data that can be trusted for decision-making processes involving quality assurance and safety evaluations. By identifying all relevant oligomers present in a given sample, this service supports the design changes necessary to minimize risks associated with unintended chemical exposures from medical devices.
Our team of experienced analysts uses state-of-the-art equipment capable of detecting down to nanogram levels, ensuring high accuracy and repeatability across multiple tests. Reporting is comprehensive, including detailed chromatograms, quantitative results, and recommendations for further investigation or process improvements based on findings.
This approach not only enhances product safety but also contributes positively towards sustainability goals by promoting the use of safer materials throughout design cycles.

Use Cases and Application Examples
In the medical device sector, this service is used to analyze extracts from various materials commonly employed in manufacturing processes. These include plastics, adhesives, coatings, and other substrates that come into direct contact with patients during use.
- Evaluating extractables from polyurethane foam used in orthopedic implants.
- Characterizing leachables from silicone rubber seals utilized in cardiovascular devices.
- Analyzing biocompatible polymers such as polycarbonate urethanes found in various implantable components.
The results obtained from these analyses provide invaluable information to quality assurance teams and R&D departments. They help ensure that only safe materials are used, thereby protecting both the manufacturer’s reputation and patient health.
For instance, a recent case involved an investigation into potential contaminants in a new generation of hip prostheses. Using HPLC-ELSD, our laboratory identified trace amounts of ethylene glycol monomethyl ether (EGME), known to be harmful if ingested. This discovery prompted immediate changes to the manufacturing process, resulting in safer products for patients.
Another example comes from a pharmaceutical company developing a new drug delivery system. By applying this service during formulation stages, they were able to optimize their formula, reducing unwanted side effects while maintaining effective drug release profiles.
